Battery cover latching assembly for portable electronic device

Abstract

A portable electronic device ( 80 ) has a battery cover ( 100 ) and a housing ( 300 ) releasably mounted with a battery cover latching assembly ( 200 ). The battery cover has a receiving hole ( 114 ). The housing has a positioning member ( 316 ). The battery cover latching assembly includes a latching member ( 201 ) and a resilient member ( 202 ). The latching member has a locking portion ( 2019 ). The resilient member has a first end ( 2021 ) and a second end ( 2022 ). The first end is mounted in the latching member. The second end is mounted with the battery cover. The latching member is installed in the receiving hole. The locking portion is engaged with the positioning member thereby mounting the battery cover to the housing. When the latching member is forced to move relative to the battery cover, the resilient member is twisted thereby making the latching member to move in an opposing direction.

       6 . The battery cover latching assembly as claim in  claim 1 , wherein the resilient member is substantially in a form of a cylinder and is located parallel to a pivot axis of the latching member.  
   
   
       7 . The battery cover latching assembly as claim in  claim 6 , wherein the first end of the resilient member extends in an axial direction and the second end of the resilient member extends in a radial direction.  
   
   
       8 . A portable electronic device comprising: 
 a battery cover having a receiving hole;    a housing having a positioning member, and    a battery cover latching assembly releasably connecting the battery cover and the housing, the battery cover latching assembly comprising:    a latching member with a locking portion; and    a resilient member being mounted between the latching member and the battery cover;    wherein the latching member is rotatably installed in the receiving hole of the battery cover, the locking portion is engaged with the positioning member thereby mounting the battery cover to the housing, when the latching member is forced to rotate relative to the battery cover, the resilient member is twisted thereby creating a force to enable the latching member to move in a substantially opposing direction.    
   
   
       9 . The portable electronic device as claimed in  claim 8 , wherein the latching member further includes two mounting poles extending respectively from two opposite ends thereof, the battery cover has two mounting holes defined therein, and the mounting poles are rotatably received in the mounting holes.  
   
   
       10 . The portable electronic device as claimed in  claim 9 , wherein the resilient member surrounds one of the mounting poles.  
   
   
       11 . The portable electronic device as claimed in  claim 9 , wherein the latching member has a body, two mounting feet extend from two ends of the body towards a same direction, and the two mounting poles respectively extend from the two mounting feet.  
   
   
       12 . The portable electronic device as claimed in  claim 9 , wherein the battery cover includes an end wall, the receiving hole is defined in the end wall, two protrusions extend from the end wall and respectively adjacent to the receiving hole, and the mounting holes are respectively defined in the protrusions.  
   
   
       13 . The portable electronic device as claim in  claim 8 , wherein the resilient member is substantially cylindrical in shape and is located parallel to a pivot axis of the latching member.  
   
   
       14 . The portable electronic device as claim in  claim 13 , wherein the resilient member has a first end and a second end, the first end extends in an axial direction, and the second end extends in a radial direction.  
   
   
       15 . A portable electronic device comprising:
